Trade names

(Examples)
Properties vulcanized rubber / polymer Application examples

Natural rubber
(cis 1.4 Polyisoprene from bio synthesis) NR SMR
Crepe General purpose rubber with balanced physical properties. Non-ageing and weathering resistant only with suitable stabilization. Tires, conveyor belts, moulded articles of all kinds

Isoprene rubber
(cis 1.4 Polyisoprene from technological synthesis) IR Natsyn
Cariflex IR Like NR Like NR

Butadiene rubber or polybutadiene BR Buna CB General purpose rubber almost exclusively used in cuttings. High elasticity, drive stability and cold flexibility. Compound element: use similar to NR

Butadiene/styrene rubber
(copolymeride made of butadiene /styrene) SBR Buna SB
Cariflex S Frequently used general purpose rubber. Non-aging and weathering resistant only with suitable stabilization. Tires, belts, moulded and extrusion artcles

Chloropren
(trans 1.4 polychlorbutatiene) CR Neoprene
Polychloropreen Rubber with a relatively high resistance to flames, weather and aging. Medium resistance to oil and fuel. Belts, v-belts, moulded and extrusion articles

Nitrile rubber
(copolymeride made of butadiene) (Acrylonitrile) NBR Buna N High swelling resistance to oil, fat and fuel. Degrees of resistance, elasticity and cold flexibility depend on the acrylonitrile content. Oil, fat and fuel resistant articles, roller coatings, hoses

Hydrogenated nitrile rubber HNBR Perbunan There are also hydrogenated types (HNBR) with higher resistance to ozone and aging.

EPDM rubber
(terpolymere made of ethylene/propylene and diene component) EPDM Buna AP
Keltan
Dutral High resistance to aging, weather and heat. High resistance to boiling water, steam, washing and flushing agent. Moulding and extrusion articles

Butyl rubber
(copolymer made of isobutylene and little isoprene) IIR Butyl rubber High air- tightness, good damping properties and heat resistance. There are also special halogenated types (BIIR, CIIR). Car and bicycle tubes, antivibration components

Chlorhydrine rubber
(polyepochlorhydrine, copolymerizate with ethylene oxide where appropriate) CO
ECO Hydrin High resistance to oil, fat, fuel, heat and oxygen. Oil, fat and fuel resistant articles

Chlorosulfonated polyethylene CSM Hypalon Similar to EPDM yet better swelling resistance to oil, fat and fuel. High resistance to chemicals and flames. Moulding and extrusion articles, roller coatings, container linings

Acrylate rubber
(polyacrylate) ACM Hytemp Excellent resistance to oil,
fat and fuel especially to hypoid oil. Low cold flexibility. Moulding articles

Fluoro rubber
(copolymer made of fluorinated
compounds) FPM Viton ®
Fluorel
Technoflon Moulding articles, container linings Moulding articles, container linings

Silicone rubber
(polymethylsiloxane with phenyl and/or vinyl groups where appropriate) VMQ Likonsil
High resistance to aging, weather and heat. Extremely high cold resistance. Medium resistance to oil and fuel spray Food qualities, medical pharmaceutical articles

Fluorosilicone Rubber FVMQ Likonsil-F High resistance to aging, weather and heat. Extremely high cold resistance. High resistance to oil and fuel.

Perfluoro Rubber FFKM Isolast ®

Thermoplastic elastomers TPEiner linings TPE/TPU/TPSi Varies articles, container linings Moulding,overmoulding and extrusion articles

Special qualities

In the laboratories special compounds are delevoped when standard qualities do notfulfill specific requirements.
Compound properties are constantly tested with special equipment to assure compliance with specifications.
